The MAASH technique is a hip prosthesis surgery, that is, it is the primary replacement of the hip with a prosthesis. This is one of the most relevant surgeries since it improves people’s quality of life.
Despite advances in materials and new prosthesis designs, there continue to be certain complications such as dislocation of the implanted components, loosening and infection. The MAASH technique, introduced in 2013, is a new working philosophy based on the preservation of the fundamental stabilizing elements of the hip.
This technique is not a new surgical approach, but a method based on the preservation of the stabilizing and essential elements of the hip joint. Maintains the natural biomechanics of the hip, changing the classic concept of muscle-based prosthetic balance to the concept of capsular balance.
Advantages of the MAASH technique
When the Traumatology specialist implants a hip prosthesis using the MAASH technique, the chances of dislocation are minimal and the duration of the implanted components will probably be longer.
Among the advantages offered by this technique are the following:
- High stability of the prosthesis with minimal likelihood of dislocation.
- Control of the difference in length of the lower extremities.
- It requires less hospitalization time. Hospitalization is approximately three days.
- Rapid recovery that allows a quick return to routine and professional activity.
Who can undergo the MAASH technique?
All those who do not present contraindications for a hip replacement by prosthesis can benefit from the MAASH technique.
It is indicated for people who have not previously undergone hip replacement surgery. That is, it requires that the hip capsule is intact. On the other hand, it is ideal for people with osteoarthritis of the hip who wish to continue practicing sports.
Since it does not depend on muscle balance but on capsular balance, it can be used in cases of high risk of dislocation, such as people with neuromuscular diseases, dementia, Down’s trisomy, intracapsular hip fractures and rescue of failed osteosynthesis of fractures of the femoral neck, among others.
